The aim is to increase the sustainability of existing buildings, by reducing their energy consumption needs, for heating and cooling, and the corresponding gaseous emissions, while increasing their users\u2019 comfort. Firstly, an analysis of the advantages and disadvantages of several thermal insulation solutions for fa\u00e7ades was carried out, supported in current literature. Then, a survey of real retrofitting scenarios and interviews with experts was completed, to allow the selection of the most adequate thermal insulation techniques. Finally, as a result of this study, the discussion of retrofitting strategies was carried out to support the designer\u2019s decision process, based on a flowchart with complementary tables, discussing the best thermal retrofitting technique to be implemented on old buildings\u2019 fa\u00e7ades, case-by-case.<\/jats:p>","DOI":"10.3390\/designs4040045","type":"journal-article","created":{"date-parts":[[2020,10,28]],"date-time":"2020-10-28T11:43:06Z","timestamp":1603885386000},"page":"45","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Old Buildings\u2019 Fa\u00e7ades: Fieldwork and Discussion of Thermal Retrofitting Strategies in a Mediterranean Climate"],"prefix":"10.3390","volume":"4","author":[{"given":"Diana","family":"Corr\u00eaa","sequence":"first","affiliation":[{"name":"CERIS, DECivil, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Av.
